Does Factory Restore Reset Font?

Hi, I am currently out of the house, but I installed a font changing app for my Moto X (4.4.2, 1st gen., rooted with TowelPie) my question is if I unroot (hard reboot phone, as TowelPie is a temp. root) and then do a factory restore, will my font restore to default? I've installed a horrible font that looks snazzy in preview, but is terrible in use. I was a moron and didn't make a backup before hand. I have 2 moto x's at home. If I copy paste the /system/fonts from a stock X to my rooted one, will the font reset? Is it safe? How can I go about doing it? Should I just factory restore? Thanks!!
